Only built relatively recent in 1899, it was a summer retreat for 3 emperors before becoming a park in 1947 after World War II.

What park grounds are quite vast and beautiful with gardens and creeks. However property is only about 1/3 of the original size.

With 106 rooms, there are corridors that surround and connect the rooms, some secretly. It costs ¥500 and you could easily spend half a day walking through the rooms, around the gardens and eating ice-cream or soup at the restaurant area of the park.

Closed Tuesdays and If that's a national holiday, it's closed the following Wednesday, too. Open 9-5pm, winter 9-4pm
